Solve : Open and Read from file with MS-DOS? |
|
Answer» I was wondering if anyone knows how to open an existing file and read line by line using MS-DOS? Also does anyone know how to parse out an existing value and replace it with a new value within a file using MS-DOS? there are couple things I want to do....Depends on what you want to do, Code: [Select]gawk "{ #do processing line by line, } " file.txt Quote 2) Second thing I want to do is I have an .ini file that I want to modify. I will need to search for a string, deleted the existing string value and replace it with new string values.Using gawk again code snippet, again depending on what you want to do Code: [Select]gawk " { #read line by line, search for pattern then substitute }" myfile.ini Let me rephrase what I want.... I want to open a file that contains a list of values. Ex values in File: ABC DEF GHI JKL Then read in each value one at a time. Ex. set %value1%=ABC set %VALUE2%=DEF set %value3%=GHI set %value4%=JKL Can MS-DOS automate this? Another way to understand what I want is using DOS to open a file and read in line by line. ThanksMS-DOS, really? What version? Code: [Select]@echo off set idx=0 for /f %%x in (input.txt) do ( call set /a idx=%%idx%%+1 call set value%%idx%%=%%x ) You can try this. I don't remember when the for /f switch was introduced. After running, use the set command at the prompt to see your variables. Good luck. well I am not sure what version of MS-DOS I am using since I have limited access. I know what version of EDITOR in MS-DOS (2.0). As for the for loop... I tried it and it works great. So now instead of 10 pages of code I only have 2 pages of code since I won't have to copy and paste same code over and over again. Thx! |
